Interesting Article.....Maybe? :http://phandroid.com/2013/02/05/android-4-2-2-could-roll-out-this-month/
Obviously, I can only speak for myself, but I am not experiencing any issues with Bluetooth or Pinch to Zoom, those all seem to work perfectly fine for me,
My issue is the phone and the at&t network. In certain parts of the country while making a phone call the phone hard hand offs to 2G and only after the call is completed does the phone hand off again to the 3G network.
I wonder if 4.2.2 fixes that issue or if this is something that is going to plague the handset for its entire existence.
